Differential pressure measurement on gas hot water heaters or on filters of air conditioning systems, and also flow measurements in ventilation ducts using a Pitot tube: the compact testo 510 differential pressure measuring instrument, which comes with a silicone connection hose and other useful accessories, can help you maintain and install systems in the sanitary and HVAC sector.

This temperature measuring instrument is particularly practical because it enables virtually any kind of temperature measurement. Whether for surface, air or immersion/penetration measurement: with the testo 925 you can rely on our all-rounder in heating engineering, the sanitation sector and refrigeration and air conditioning technology.

An attachable temperature probe and a radio temperature probe can be connected

Large range of fast temperature probes on offer for surface, air or immersion/penetration measurement (optional)

The testo Smart Probes AC & refrigeration test kit is ideally suited for testing air conditioning and refrigeration systems and installing them. The large testo HVAC softcase enables the measuring instruments to be conveniently transported and ensures that they are always to hand when they are needed.

The testo Smart Probes Refrigeration set is ideal for carrying out servicing and troubleshooting on air conditioning and refrigeration systems, as well as for installing them. The robust testo Smart Case enables the measuring instruments to be conveniently transported and ensures that they are always to hand when needed.

The functional testing of ventilation and air conditioning systems includes monitoring the flow speed in ventilation ducts. If the air flow velocity and volumetric flow are not set correctly, the room air quality may suffer. The testo 425 thermal anemometer measures the flow speed and automatically calculates the volumetric flow.

Temperature and flow measurement as well as volumetric flow calculation

The testo 830-T1 infrared thermometer allows efficient, non-contact surface temperature measurements to be carried out. The IR thermometer will leave you well equipped, especially for control readings in trade and industry: The gun-style design is easy to handle and the integrated processor provides accurate measurement results.

The testo 625 thermohygrometer comes into its own in all situations where the right indoor climate is crucial, for example in archives, storerooms, greeenhouses and buildings. The testo 625 also calculates the dew point and wet bulb temperature quickly and accurately.

Non-contact measurement on tightly packed cables is really easy and reliable with the testo 770-3 clamp meter. Its innovative grab mechanism will make your work easy. The most powerful model in the clamp meter series, it offers lots of additional functions for those challenging tasks that you are faced with on a daily basis, e.g. communication with the smartphone app via Bluetooth.

The testo 549 digital manifold offers many advantages in comparison with analog manifolds: the instrument will make it easier for you to work on refrigeration systems and heat pumps. With its integrated temperature measurement and automatic calculation of superheating/subcooling, you can now do away with additional measurements and manual comparisons (when using an optional clamp probe). You can also use the manifold for 60 current refrigerants.
